The league's Department of Player Safety issued the suspension Thursday after a hearing.
Nashville's Ryan Hartman suspended one game for an illegal check to the head on Colorado's Carl Soderberg. https://t.co/uMMlHfRDX9— NHL Player Safety (@NHLPlayerSafety) April 19, 2018
Hartman was penalized for charging Soderberg at 4:52 of the third period. Soderberg was skating across the blue line and had just passed the puck to a teammate when Hartman hit him in the head.
The NHL noted Hartman took a poor angle and picked Soderberg's head for the main point of contact and then delivered a hit "with substantial force."
Hartman has been fined once in his 162-game NHL career. The Predators lead their first-round, best-of-seven series 3-1 and can clinch Friday night at home.
